SPECIFICATION forming part of Letters Patent No. 793,054, dated June 27, 1905.

Application filed March 14, 1904- e fl NO- 197,966.

To (all whom it may concern/.-

Be it known that I, HENRY H. OLoUen, a citizen of the United States, and a resident of Elyria, Lorain county, Ohio, haveinvented certain new and useful Improvements in Railway-Tie Plates and Means for Securing a Rail Thereto, of which the following is a complete specification.

This invention relates to tie-plates, and relates particularly to tie-plates of the general type which forms the subject-matter of an application for Letters Patent of the United States, filed by me in the Patent Ofiice concurrently herewith, Serial No. 197,965.

The object of the present invention is to provide a modified form of means for seeur ing the rails to the tie-plates from the means shown, described, and specifically claimed in said application above identified.

The present invention consists of the various features, combinations of features, and details of construction hereinafter described and claimed.

In the accompanying drawings a tie-plate and securing means embodying the invention of the presentapplication are fully illustrated.

Figure 1 is a top plan view of a tie-plate, showing a rail secured thereto by means embodying my present invention. Fig. 2 is a sectional view thereof on the line 2 2 of Fig. 1. Fig. 3 is an enlarged perspective view of a clamping-dog forming part of the securing means. Fig. 4. is an enlarged sectional view on the line a 4 of Fig. 1. Figs. 5, 6, and 7 are views similar to Figs. 1, 2, and 3, respectively, illustrating a modification of the securing means shown in said Figs. 1, 2, and 3. Figs. 8 and 9 are views similar to Figs. 5 and 6, illustrating a modified form of means for securing the clamping-dogs in adjusted position. Fig. 10 is an enlarged sectional view on the line 10 10 of Fig. 8, and Figs. 11 and 12 are enlarged detail views.

Referring now to the drawings, 1 designates a tie-plate to which the rail 2 is adapted to be secured in the following manner: Formed in the tie-plate l are slots 3, which are disposed outside of and extend oliliquel y relatively to the rail-seat on said tie-plate. l

Secured in the slots 3 by means of suitable heads 4: thereon, so as to be movable lengthwise of said slots, are dogs 5, the inner ends of which are adapted to extend over the bases of the rails, the relation being such that as said dogs 5 are forced or driven lengthwise of the slots 3 toward the rail 2 the ends thereof, which extend over the rail-bases, will be drawn into strong engagement therewith, thereby clamping the base of said rail firmly to the tie-plate and operating to secure said rail firmly in position upon its seat.

In the preferable construction (shown in Figs. 1 to l, inclusive, of the drawings) the slots 3 are T-slots, and the inner ends of the dogs 5, which engage the bases of the rails, extend at an angle relatively to the corresponding sides of the heads 4, the relation being such that at the sides of said dogs designed to be inserted into said T-slots 3 first the surfaces on said dogs which engage the rail-bases will be directly opposed to the shoulders on the heads l, which engage the inner fianges of the T-slots 3, as shown at 6, Fig. 3, the relation being such that as the dogs are driven or forced into engagement with the bases of the rails the opposed surfaces or shoulders 6 will exert a gripping or clip action, tending to draw the rails and tie-plates together, the force of which will be additional to the ordinary lever action exerted by said dogs. As shown in Figs. 5 to 12, inclusive, the slots 3and dogheads 4 are made in the form of dovetails. As shown, the dogs 5 are cut away or recessed at the points where they engage the bases of the rails, said recesses conforming substantially to the shape of said rail-bases where they are engaged by said dogs, as shown at 7. This, however, is not essential, as the form of said dogs may be varied without departure from my invention. Due to the fact that the slots 3 extend obliquely to the rail-seats it is obvious that the same tie-plates may be used with rails having bases of different widths. After the dogs 5 have been forced or driven into desired engagement with the bases of the rails they are adapted to be secured in adjusted position by suitable means.

As shown in Figs. 1 to 7, inclusive, said Lfl.

dogs are adapted to be secured in adjusted position by means of set-screws 8, threaded through said dogs and adapted to bear upon rigid portions of the tie-plates 1, as shown the bottoms of the slots or grooves 3. In what I now consider the preferable construction, however, said dogs 5 are adapted to be secured in adjusted position in the following manner: Formed on the bottoms of the slots or grooves 3 are teeth 9, the sides or faces of which away from the outer ends of said slots are preferably vertical, or substantially so, and the opposite faces of which toward the outer ends of said slots are preferably upwardly and rearwardly inclined. Fitted to suitable hearings in the dogs 5, so as to be freely movable toward and from the teeth 9, are blocks 10, formed on the lower surfaces of which are teeth 11, the shape of which corresponds to the shape of the teeth 9 on the tie-plate, the front faces thereof being substantially vertical and the rear or inner faces upwardly and rearwardly inclined. To prevent turning of the blocks 10, which would bring the rackteeth 11 thereon out of alinement with the teeth 9, suitable means are provided to prevent turning of said blocks in their bearings. As shown, this is effected by making said blocks square or rectangular in cross-section.

To provide for disengaging the teeth 11 on the blocks 10 from the teeth 9 on the tie-plate, means are provided as follows: Formed on the blocks 10 are shanks 12, which are fitted to and extend upwardly through suitable openings formed in the dogs 5 and are of such length that they will project above the tops of said dogs. The upper ends of the shanks 12 on said blocks 10 are screw-threaded, and adjusted thereto are nuts 13. WVith this construction it is obvious that turning the nuts 13 when they bear against the tops of the dogs 5 will operate to raise the blocks 10 and to withdraw the teeth 11 thereon from engagement with the teeth 9, thus making provision for releasing the dogs 5 when desired. It is also obvious that the blocks 10 will be supported in raised position until the nuts 13 are again unscrewed. hen inserting the dogs 5 into the slots or grooves 3, the blocks 10 will preferably be secured in raised position, so Y as to be entirely clear of the teeth 9. It is obvious, however, that even should said blocks be in lowered position the inclination of the faces thereof will operate to raise-them as said dogs are forced or driven inwardly, so that said blocks will not interfere with the inward movement of said dogs. After the dogs 5 have been forced or driven into desired engagement with the bases of the rails the nuts 13 will be unscrewed, allowing the blocks 10 to fall, thereby bringing the teeth 11 thereon into engagement with the teeth 9 on the tie-plate, which will operate in an obvious manner to prevent movement of the dogs 5 in a direction to release the rail until said blocks are again raised in the manner heretofore described.

WVhile I have herein shown two clamping devices on each tie-plate disposed on opposite sides of the rail-seat, it is obvious that each tie-platemay be provided with but a single set of securing devices, successive plates comprising securing devices disposed on opposite sides of the rail-seats thereon.

Any desired or approved means may be used for securing the tie-plates 1 to the ties. As shown, the tie-plate 1 comprises a web or flange 14, adapted to be secured to the metal core of a concrete tie in the manner fully shown, described, and claimed in an applicameans for securing a rail thereto, said means comprising a slot in said plate which extends obliquely to the rail-seat, a clamping-dog and a head thereon secured in said slot, the inner end of said dog being designed and adapted to engage the base of a rail and the outer end thereof resting in contact with the surface of said tie-plate at the side of said slot remote from the rail-seat, substantially as described.

3. The combination with a tieplate, of means for securing a rail thereto, said means comprising a T-slot formed in said tie-plate which extends obliquely to the rail-seat, a clamping-dog and a head thereon which is secured in said T-slot, the relation being such that at the side of said dog designed to be inserted into said T-slot first, the end of said dog which engages the rail-base will beopposed to the shoulder on the head of the dog which engages the inner flange of said T-slot, substantially as described.

4- The combination with a tieplate, of means for securing a rail thereto, said means comprising a T-slot which extends obliquely to the rail-seat, a clamping-dog, and a head thereon which is secured in said T-slot, the end of said clamping-dog which engages the rail-base extending at an angle relatively to the corresponding side of the head on said clamping-dog in such manner that at the side of said dog designed to be inserted into said T-slot first, the surface of said clamping-dog which engages the rail-base will be directly opposed to the shoulder on the head of the dog which engages the inner flange of said T-slot, substantially as described.
